There was to be a Shirt cockers brigade last year during the Critical tits ride. Anyone seen taking pictures of the CT ride would get a bunch of SC in their way. Shirt Cockers to save the day! Unfortunately, it didn't happen due to the big dust storm.

I've seen the pants cannon deployed once by the BRC rangers. They were using it wrong.
Circling the Naked Bike Ride event in beat up jeeps firing undershorts at participants who were
nude but not shirtcocking.
